C[Black plans to build a large scale structure at the top, but ...];
W[ph];B[oh];W[pi];B[oi];W[pj];B[nk]
C[... in this game, Black gives up too much on the right side for the moyo.  Note that White's 20 points of territory is not the most important feature of this position.  What is important is that White's group has a strong live group, and White has sente.];
W[kc]
C[In the game, White invaded here.  But this move is not good, being too deep and too early.  Instead, White should have played on the lower side first.

In any event, how should Black respond now?];
B[ic]
C[Correct.  Black pressures simply to make profit.];
W[nb]
C[Now White has to scramble to live.]

C[Another calm good move.];

C[Black makes another simple move that makes territory and keeps White's group unsettled.];

C[White can jump out, but ...];
B[kg]
C[... Black can block here.  White cannot get out.  Even if White lives, which isn't a foregone conclusion, Black will build useful center power.]

    C[Looks good, but a mistake.];
    W[mb];B[lc];W[lb];B[kd];W[jc];B[jd];W[ib];B[hb];W[jb];B[fi]
    C[Black trades top side territory for central power.  But White's top group is secure, so if White can reduce Black's center moyo, White is back in the game.]

    C[This splitting move may seem like a risky move, but actually is the easiest and safest way to play.];
    W[of];B[qn];W[ol];B[ni];W[mf];B[ld]
    C[Black already has secured 30 points of territory at the top and 10 points in the lower right corner.  White has no points of territory on the right.  And because White has two groups that will have to make life independently, Black's 2 middle right stones are in no trouble.

Black has a great power advantage and has taken control of the game.]
